Edge TechnologyTool Post Indicator Deluxe

Just buy it. Its worth every penny

One thing I need (to make this indicator more useful) is a second internal pivoting actuator that is about twice as long. I was checkinhg the jaws of my 3 jaw chuck and could only go as far as the surfaces of most of the reversable jaws. I want to also check the grip surfaces of the master jaws to make sure that they match the height of the removable ones.Another thing would be to change the attachment arm of that assembly to place it on the outside of the pivot arm. This would allow the assembly to fit in smaller bores and go deeper into them.

Works great for setting up and centering off bore diameter for barrel threading
